| 摘 要： | 对赛里木湖贝加尔雅罗鱼的生长、食性和繁殖力等进行了观测研究．结果表明，贝加尔雅罗鱼在赛里木湖生长缓慢，1^ 龄平均体长4．5cm，11^ 龄为23．6cm；体重与体长的相关关系为W=0．142971L^3.072634。雄鱼最小性成熟年龄为2^ 龄。雌性最小性民熟年龄为3^ 龄，绝对怀卵量平均为21520粒，相对怀卵量为131粒／g，繁殖期在5月底至6月底．食物组成主要为钩虾和西藏拟骚．

Research of the Growth of Leuciscus Leuciscus Baicalensis in the Sailimu Lake |
| |
| Abstract: | This paper deals with the analysis of feeding habits, growth and fecundity of Leuciscus leuciscus baicalensis in the Sailimu Lake. The results indicate that the growth is very slow in the Sailimu Lake. The average body length of 1\++ age group and 11\++ age group are 4.5cm and 23.6cm respectively. The regression equation of the body weight(W)based on the body length (L) is: W=0.142 971L\+\{3.072634\}. The males reach the first maturity in the autumn of their third year of life, but the females are the fourth year of life. The average absolute fecundity is 21.52 thousand eggs, the comparative fecundity is 131egs/g. The spawning season starts from the end of May to the end of June. \$Leuciscus leuciscus baicalensis\$ in the Sailimu Lake mainly feed on grammarus and Daphiopsis tibetana. |
